Abstract

A tool for mfg. hollow profiles is new. The female part of the tool is made of metal and the male part is made of a heat and chemical resistant rubber extruded crude profile. The crude profile has a metallic bored profile carrier opt. having alignment aids for the extruded rubber profile. The pressurising oil can be sent through the male part at a low flow rate using a heating arrangement. USE/ADVANTAGE - The tool bears high pressures which were previously only possible using heavy, costly machines. Used for mfg. hollow profiles out of polyester prepregs (SMC)

Description

Zweck dieser Erfindung ist, durch ein neuartiges Preßverfahren teuere Maschinen und Werkzeuge zu umgehen.The purpose of this invention is to use a novel pressing method to make it more expensive Bypass machines and tools.

Die Verformung dieser Preßmasse setzt voraus, daß sie unter hohem Druck verarbeitet wird (etwa 60 bar). Außerdem ist für den Materialfluß eine Temperatur von ca. 140°C erforderlich.The deformation of this molding compound presupposes that it is under high pressure is processed (about 60 bar). There is also a for the material flow Temperature of approx. 140 ° C required.

Das Werkzeug besteht aus einem metallischen Unterteil (1) mit Abschluß­ deckel (2). Beheizt sind diese Werkzeugteile elektrisch (3).The tool consists of a metallic lower part ( 1 ) with end cover ( 2 ). These tool parts are heated electrically ( 3 ).

Eingelegt in diese Matrize ist die zu verpressende Masse (4). Diese Preßmasse umschließt die Patrize des Werkzeugs (5), die aus einem den Innenkonturen des Hohlkörpers angepaßten extrudierten Formteil aus einer Kautschukart besteht (6).The mass to be pressed ( 4 ) is inserted into this die. This molding compound surrounds the male part of the tool ( 5 ), which consists of an extruded molded part made of a type of rubber and adapted to the inner contours of the hollow body ( 6 ).

Diese Kautschukart ist wärmebeständig, chemisch beständig gegen das Druckmittel, abriebfest und hat eine hohe Bruchdehnung und liegt bei den geforderten Werten der Ausdehnung und Zusammenziehung innerhalb der Proportionalitätsgrenze.This type of rubber is heat-resistant, chemically resistant to that Pressure medium, abrasion-resistant and has a high elongation at break and is included the required values of expansion and contraction within the limit of proportionality.

In dem extrudierten Kautschukprofil ist ein metallischer Profilträger, innen hohl um das von der Hydraulik kommende Druckmittel durchzulassen.In the extruded rubber profile is a metallic profile carrier, hollow inside to let the pressure medium coming from the hydraulic system pass through.

Es können ebenfalls Richtungshilfen für das extrudierte Formteil ange­ bracht sein (7).Directional aids for the extruded molded part can also be introduced ( 7 ).

Das hydraulische Druckmittel Öl oder Preßwasser wird bereitgestellt aus einer Akkuanlage. Es wird druckreduziert auf den benötigten Druck. Eben­ falls wird diese Flüssigkeit auf die erforderliche Temperatur für das Fließen der SMC-Masse gebracht. Damit immer diese Temperatur zur Verfügung steht für die Menge der Preßmasse ist es vorgesehen, nach Erreichen des Drucks im Werkzeug eine weitere Menge Druckflüssigkeit aus einem Wärmetauscher in ständigen Fluß in die Patrize zu bringen.The hydraulic pressure medium oil or press water is provided from a battery system. The pressure is reduced to the required pressure. Exactly if this liquid gets to the required temperature brought for the flow of the SMC mass. So always this temperature is available for the amount of molding compound it is intended to If the pressure in the tool is reached, another quantity of hydraulic fluid to bring from a heat exchanger into the patrix in constant flow.

Nach Eintreten der Polymerisation der flüssigen Formmasse wird zunächst die Bewegung des Heizmittels eingestellt. Danach wird der Druck aus der Patrize gelassen. Das extrudierte Patrizenprofil schwindet auf die Ausgangsstellung im drucklosen Werkzeug und ermöglicht das Entformen des gewünschten Polyester-Körpers. Sämtliche Werkzeugteile werden dazu in die Ausgangsstellung gebracht.After the polymerization of the liquid molding compound occurs, first of all the movement of the heating medium is set. Then the pressure is off left the patrix. The extruded male profile disappears onto the Starting position in the pressureless tool and enables demolding the desired polyester body. All tool parts become part of it brought into the starting position.

Wenn das Hohlprofil symmetrisch ist, entfällt das Richten des gepreßten Körpers. Es kann dann unmittelbar nach der Enformung weiterverarbeitet werden.If the hollow profile is symmetrical, there is no need to straighten the pressed one Body. It can then be processed immediately after the deformation will.

Das Werkzeug selbst nimmt die Kräfte auf, die normalerweise schwere teure Maschinen aufnehmen (8).The tool itself absorbs the forces that normally heavy, expensive machines absorb ( 8 ).

Die Kosten des Werkzeugs sind ein Bruchteil der Kosten bisher nach herkömmlichem Verfahren benötigter Werkzeuge.The cost of the tool is a fraction of the cost so far conventional method of tools required.
